HARRY IB. MCNULTY, OF EAST CLEVELAND, OHIO, ASSIGNOR, BY MESNEASSIGNMENTS,

TO THE UNITED STATES PHONOGRAPH COMPANY, 0F CLEVELAND, OHIO, A CORPO-RATION OF lOHIO.

PHONOGRAPH.

To all whom t n ay 'concern Bc it known hat I, HARRY B. MCNULTY,

'a citizen of the United States, and a resident of East Cleveland,county of Cuyahoga, and Sta-te of Ohio, have invented a new and usefulImprovement in Phono-- graphs, ot' which the following isa'specitication, the principle of the invention being herein explainedand the best mode in which l have contemplated applying that printwominute and four minute records.

To eil'ect such adaptation of the machine, it is necessary that thereproducer be fed along the record at a different rate 0f speed in eachcase, and that a stylus of a vdiii'erent character, corresponding to thetineness of the thread, be properly positioned in the one case to playo-n the tine thread, in the other upon the coarse thread. One form ofmechanism for conjointly eiecting thel two adjust-ments referred to isillustrated in my co-pending application, Serial No. 463,942, filedNovember 23, 1908, and the present invention is in part an improvementof such earlier mechanism, and in part an adaptation of the same toseveral variant forms of reproducer from thev preferred form there"shown. l

, Said invention, then, consists of the means hereinafter fullydescribed', and particularly pointed out in the claims.

The annexed drawings and the following description sc t 'forth indet-ail certain mechanism embodying the invention, such disclosed means'Y constituting, however, but several of thefvarious mechanical forms inwhich the principle of the invention may be used.

In said annexed drawing -Figure 1 is a transverse sectional view of arphonograph embodying my several improvements in one approved form; Fig.2 is a similar view of the reproducer andihat portion of the carriagevin which said repreducer is seated,

showing parts of the lattern a diefeent opspecification of Lettersraient.

l; Fig. 3 is a bottom plan view of an actuating cam member that forms afeature of `the machine; Figs. 4, -5 and 6 respectively illustrate 1ndiiferent operative positions, a

development of one of the cam elements of such cam member; Fig. 7 is aperspective view of another detail of the machine,'viz.-

the key whereby the adjustment of the reproducenstylus is secured; Fig.8 is a secves tional view of the reproducer and the portion 'of itscarriage corresponding to. that of F1g. l but showing the adaptation ofmy invention to a diiferent construction of stylus lever; Figs. 9 and l0similarly illusother forms of stylus lever; and Fig. l1 shows a `det-ailof t-he construction of Figs. 8 and 9 in modified form.

AIt has not been deemed necessary for prestrate the adaptation of suchinvention to ent purposes to illustrate the general construction of thephonograph in greater detail than. is aorded inthe sectional view of Fig. 1 wherein the supportfor the record receiving mandrel A 'is notshown, but merely its position relatively to the base A. and to the waysa upon which is slidably .mounted the carriage B for the reproducer.Movement of this carriage along such ways is secured by connectlng thesame with v one or the other of-two feed screws C C lying below andparallel with its direction of .movement, such engagement being had .by

means of plungers B B2 recoprocably mounted in the carriage, the lowerends ofwhich are in the form of sectional nuts gage the upper ends Z2 bpf t-he plungera4 respectively.

The disk B3, in the form shown, isv a composite construction, being madeup of an uppersection bearing' the cam 64 Vjust reerred to, and a lowersection incased within the carriage body. Such. lower section 1s,however, fixed to the upper section so as to `rotate therewith, justasthough said sections Were integral.

.,JThe. under face of the lower section of camdisk B3 (see Fig. 3) isprovided with a raised edge b'forming a cam adapted to laterally engagea key D that is both rota- 5 tably and longitudinally'movable within asleeve D -pivoted to the under side of the rearwardly projecting annularportion B4 of the carriage wherein the reproducer E is seated wheninuse. Disk B3 is further provided. with a heart-shaped cam b that isadapted to terminally engage said key D to advance the same. A tensionspring d. con.v

nected with'the' outer end of the key's'erves both tolretract it and todepress its outer.; end against the operation of the cam ele':

inents'just referred to. Such raised cam edge b? however, is formed atsubstantially opposite points vin its extent with notches b that permitthe lowering of the outer end 2b of the key at fthe same time that itsretraction is rendered possible by heart-cani bs, such position ofthetwo cam elementson the under face of the disk corresponding with theposition of the cam b4 on its upper face '5 that permits operativeengagement of one or the other of the two spring pressed plungers'B B2with its feed screw C or C. Intermediate between the two notches b incam 71", so as to correspond with tha forwardly extending lportion ofheart-cam bs,

is a radially disposed pin '61 that engages a forked arm d on the rear'end of the key.

I so as to rotate thelatter first in'one'fdirection, and then intheother, depending upon the direction of movement of the cam member B?.The amount of. such rotation is accurately' determined by'means of twonotches cl2 properly spaced about the inner end of the sleeve D', andadapted to engage a pin 40 Z3 bornef'on the side of the key (see Fig.7). The portion of the sleeve lying between the two notches beingsuitably beveled, makes it necessary merely to carry the key in itsrotative movement past the center of such pin to insure aproper'p'ositioning of the key, and of the stylus lever or actuatingelement W'itli'which'` the same engages, as, and for the purpose-now tobeset fort-h.

The 'general construction ofl the reprod meer E ustrated in Figs. l and2, is the same ast-hatshown in the co-pendino ap- V plication previouslyreferred to, an includes a diaphragm (not shown), a floating weight E, atubular lever e pivoted to said 35.5 weight vand connected to salddiaphragm,

and a stylus holder erotatably held vin said lever and provided at itsforward end with a plurality ofstylusese2 adaptedE to opera- 't-ivelycontact with a record upon the mandrel Af in different positions of saidholder respectively. The rearwardly projecting end ev of the holder ismadev angular to receive the end of the key D when the latter is thrustforward, or advanced, bythe con- 6'5- jointly operated cams on the upderface of *feed-screw.

.the stud e5 with a gear e and journal in suitthe disk B3,fhe'prelimiiry estimada- Of such key` serving to raise the weight intothe positionshown inA Fi 1, whereby the v'key and the stylus hol erl areproperly alined forv the purpose in question. Pending such engagement,the rotative movement of the key takes place, andas a result, one

or the other of the styluses is brought, into said voperative position,depending upon the direction of said rotation. Thisy movement obviouslywill be correlated with the movement of a spring-pressed plunger B. orB2 into engagement with the .corresponding as has been-previouslymt11nated,'1n the construction of the stylus lever which here is shownasa bar ofthe prevailing form.` In the oterend of the bar is rotatablymounted a vertically disposed transverse 'stud e5 85 that forms thestylus holder, the latter. bearing the two styluses, e2 one of which issuit-14 able for operating on anl Ordinar record .of threads per inch,-and the ot 1er operating on a record having 200 threads per inch. Thespecific construction of such stylus holder, it may be remarked, formsno part of the present invention, being shown in fact alongwith the twoforms of Figs. 9 and 10, in U'. S. Patent No. 904,884. To au- 95tomatically effect rotation of suoli stylus holder in a manner similarto that just described in connection with the preceding form of holder,I provide the upper endv of 100 able bearings on the'under side of thefioating weight E a shaft or spindle e7, the outer end of which bears aworm es that is adapted to mesh with said gear in the`raised position ofthe stylus lever illustrated in .the figures in question. The rear endofspindle c7 corresponds with the rear end of the stylus holder in thepreceding construction, and is made of similar angular form, so that thekey operated by the cam member 11o B3 is adapted to function in the samemanner as before, first toraise the weight, and then to advance intoengagement with, and

to rotate the spindle, withthe result that the stylus holder is likewiserotatedto bring first the one, and then the other of the twol stylusese2 into desired operative position.

The 'stylus holder in the reproducer of Fig. 9 consists of ahorizontally disposed transverse stud e, which otherwise operates 12othe same as thatof Fig. 8, only la slight modification in thearrangement of the gear elo on thestud and of worm es on spindle e.being necessary. The same is true of Fig.

10, wherein the holder'consists of a sleeve 125 en rotatably mountedonthe forward end of the lever and previded with a spur gear e withwhich a pinion e, taking` the place of worm es on the forward end ofspindle e7'is adapted to mesh. 130

" such a rack and pinion it Will obviously be shaft, or

possible to secure a com lete turn of the even more, shoul this be founddesirable. l
